' WIRE FOUNDATION FOR PLASTERING.

No. 372,818. Patented Nov. 8, 1887.

74(i/5/M0 (NM UNITED STATES .T 0 all whom it may concern;

Be it known that I, CHARLES A. SAoKETT, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and use ful Improvements in Wire Foundationsfor Plastering, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to an improvement in wire foundation forplastering, which consists in a frame-work of parallel series of largewire held in place by an interlacing net-work of smaller andsufficiently fine and flexible wire.

Wire-cloth for lathing as it is now made and used is formed of straightmeshes of comparatively stiff wire, and-is sent to the market in rollsor in sheets, such sheets being caused to remain more less flat by beingcorrugated. The disadvantage of such wire-cloth in rolls is apparent toall whom necessity compels to use it. The straight meshes are found tobe loose in some portions of the wire-cloth and tight in others, thetension is not evenly distributed over its surface, and the plasterdoesnot readily adhere thereto. Besides this, after being rolled, it isexceedingly difficult to handle and to apply, since it retains thecurvature imparted in rolling, and is kinky and hard to flatten. Theflattened sheets or strips are liable to be damaged in shipping andhandling by being stepped upon or otherwise, so as to bend and stretchcertain portions so that they are difficult to flatten again.

I have found that if, instead of weaving the wire cloth in straight orsquare ineshes of stiffened wire, Itake a series of parallel thickwires, about No. 12 gage, and connect them with an interlacing net-workof fine Wire,about No. 26 gage, woven in irregular or polygonal meshes,(of which many forms are known or could be easily substituted,) this newarticle of manufacture will combine all those qualities necessary tomake a good lat-hing. The thick rigid wires should be separated fromeach other at such a distance (say from one and a half to three inches)as to give an ample bearing to the trowel. The wire lathing thus made'is stifl in the direction of its length, but flexible and easily rolledin the direction PATENT OFFICE.

of its width. This flexibility is due not only -to the fact that finewire is used, but also to the fact that such fine wire is netted insteadof being woven. In netting,the adjoining meshes are forined by strandsof. wire which are twisted round each other, thereby forming a speciesof binge which is more or less flexible according to the number of turnsor half-turns of the wire of the adj acent meshes around each other.This characteristic of netting as distinguished from woven fabrics isillustrated in one form in the drawings.

The advantages of this new article of manufacture are many. Beingcomposed, principally, of fine flexible wire net-work, it will readilyadhere to the plaster and will be much lighter than the ordinarywire-cloth composed of square meshes of thick wire. It can be readilyrolled into bundles, from which, by means of its longitudinal rigidity,it will come perfectly flat. This will be so, even'if it is tightlyrolled into a .very small compass; hence it can be readily handled andshipped, the cost of transportation will be lessened,and it will besecure from careless handling. Its flexibility in the direction of itswidth will allow the wire-cloth to be easily and perfectly fitted to anycurved surface. This in the present flat and rolled wirecloth isimpossible without the use of much labor. no bunching or sagging, sincethe thick and There can be rigid wires make the surface perfectly flatand distribute the tension evenly over the entire surface. As it isformed of a net-work,there can be no tendency for the ends to ravel, asis the casein the ordinary wire-cloth. As the whole structure projectsfrom its support less than one-fourth of an inch, it will,when applied,be entirely embedded in the plaster, and will thus be protected fromdeterioration. It insures a perfectand continuous key for the plaster,and by it tightly seals all surfaces to which it is applied, therebypreventing aircurrents. In spanning spaces, by reason of itslongitudinal rigidity, it has a stiffness out of proportion to itsrelative weight and cost as compared with other metalliclathings.

In the following drawings, Figure l is a perture when laid out flat andready for use on a flat surface. Figs. 2 and 3 are views of the same,partly rolled up into the compact form in which it may be shipped tomarket.

Similar letters refer to similar parts throughout the several views.

The thick rigid wires forming the wire frame-work are shown at AA A. Thefine wire net-work is shown at B B B.

The rigid parallel series need not be of wire. but any equivalentsupport may be used. I prefer, however, that such frame-Work be of thickwire of suificient diameter only to admit a clinch to the mortar, and tobe heldin place by an interlacing of very small wire sufficiently fineto be flexible. The thick wire can be fastened to the netting byinterlacing or by a separate wire attachment.

I am aware that prior to my invention wirecloth has been used in lathingand for other purposes, and that wire-netting has also been constructedfor other purposes. Ido not claim such; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

As a new article of manufacture, a foundation for plastering,consistingof a wire fabric formed of netting in which the strands forming adjacentmeshes are twisted around each other, substantially as described,combined with parallel rigid stifi'ening-rods secured to the fabric atintervals, substantially as and for the purpose set forth.
